PRINTING-MACHINE.

Application filed June 24,

Specification of Letters Patent.

Patented Dec. 1, 1908.

1908. Serial No. 440,145.

To all whom it may concern:

Be it known that I, MILES H. MANN, a citizen of the United States, residing at Louisiana, Missouri, have invented a certain new and useful Improvement in Printing- Machines, of which the following is a full, clear, and exact description, such as will enable others skilled. in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a side elevation of a portion of a card printing machine constructed in accordance with my invention; and Fig. 2 is a'detail view, partly in vertical section of the drive shaft of the machine.

This invention relates to printing machines, and particularly to printing machines provided with a reciprocating typecarrier and a coiiperating platen or pad for holding the articles to be printed, such, foreXample, as the card printing machine shown in my pending application Serial No. td 284, filed November 29, 1907.

The machine illustrated in the application above referred to comprises a reciprocating plunger which carries a type-carrier, and a drive shaft provided with a cam arranged inside of a yoke on said reciprocating plunger. I

The main object of my present invention is to provide means whereby the stroke of the type-carrier plunger can be varied so as to cause the type in the typecarrier to exert the same pressure on cards of different thicknesses.

Another object of my invention is to provide a shaft having a cam or arm connected thereto, a friction roller carried by said cam or arm, and means for adjusting said roller toward and away from the shaft so as to vary the degree of movement imparted to the member which the cam or arm on the shaft actuates.

Referring to the drawings which illuspractically two arms or ears between which a roller '7 is arranged, said roller projecting slightly beyond the periphery of the cam so that it will contact with the inner surface of the yoke 3 and thus reduce the friction between the yoke and the member that actuates it. The roller 7 is provided with trunnions S that project through open ended elongated slots 9 in the two arms or ears that constitute the :am 2, and yielding means, preferably a spring 10, is provided for hold ing the roller 7 in operative position. In the construction herein shown, the spring 10 consists of a piece of spring wire having a hook-shaped portion that lies in a groove 11 formed in the roller 7 and provided at its opposite end with an eve which receives a fastening device 12 that connects the spring to the cam, or to the portion of the shaft 1 that lies between the two arms that form the cam.

plunger 13 tiat is mounted in an open ing in the shaft 1 between the two arms or ears that form the cam 2, bears against the roller 7, as shown in Fig. 2, and thus holds it a slight distance beyond the periphery of the cam 2, the plunger 13 being utilized to move the roller 7 inward force that the spring it) exerts on said roller. To enable the roller 7 to be adjusted relatively to the cam 2 and thus vary the stroke of the plunger t I have provided the shaft 1 with a rod 14 that can be moved longitudinally to force the plunger 13 and roller 7 outwardly. This rod 14: is provided with an inclined face that cotiperates with an inclined face on the inner end of the plunger 13. as shown in dotted lines in Fig. 2, so that when the rod is moved inone direction it will force the plunger 13 outwardly and thus move the roller 7 relatively to the cam 2 or member in which it is mounted. When the rod 1st is moved in the opposite direction. the spring 10 will move the roller 7 inwardly. The rod 14 herein shown is round and I. have therefore provided it with longitudinally extending groove that receives a rib 15 on the inner end of the plunger 13, as shown in dotted lines in Fig. 2, so as to prevent the rod from turning. It will, of course, be obvious, however, that the rod 14: could be constructed in numerous ways to prevent it from turning and there- I fore I do not wish it to be understood that ISSOURI, ASSIGNOR TO FRANK W. BUFFUM, TRUSTEE, OF

LOUISIANA, MISSOURI.

outwardly against the my bread idea is limited to the construction herein shown. An adjusting screw 16 enters a screw-threaded opening in the end of the rod 14, and said screw is provided With a flange 1'? that bears against the bottom of .a recess 18 formed in the end of the shaft 1 so as to prevent said screw from moving inwardly when it. is rotated to impart longitudinal movement to the rod 14. The screw 16 is provided with a head 19 in which a slot is formed to receive a screw-driver 01' other suitable implement for turning the adjusting screw. The adjusting screw is locked in position by means of a nut 20 having external screw-threads that cooperate with screw-threads on the interior of the recess 18 in the end of the shaft 1, the inner end of said nut bearing against the flange 17 on the adjusting screw to clamp it against the bottom of the recess 18 in the shaft. The nut 20 is provided with an opening through which the head 19 of the adjusting screw extends, and said nut is also prqvided with a knurled head 21 in which slots 22 are formed to receive a spanner wrench.

By loosening the locking nut slightly so that its inner end will not bear upon the flange of the adjusting screw said screw can then be rotated so as to move the rod 1% longitudinally of the shaft 1 and thus move the roller 7 relatively to the cam 2 so as to vary the stroke of the plunger.

A. device of the construction above described forms a very eflicient means for accurately and quickly varying the stroke of the plunger which carries the type and overcomes the necessity of building up the pad or platen (3 when, cards of different thickness are to be operated on.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
